Five months of heat, every year, in Orangeburg County
Your air conditioner works from May through September here, with summer afternoons averaging 91°F. That is five straight months of long runtimes, and the unit does not get much of a break in between.
Orangeburg County has also seen 177 damaging wind events and 33 hail events over the past ten years, with hailstones up to 1.75 inches. The outdoor unit sits exposed to all of it. If you are installing new, anything built since 2023 has to meet a federal minimum of 14.3 SEER2, so a new system is already built to handle a long cooling season more efficiently than the one it is replacing.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated, not on a simple chart. A contractor sizes your system with a load calculation that looks at your actual house, not a guess based on the neighbor's place. Going bigger than you need isn't a safety margin, it makes the unit cool the air fast without pulling the humidity down, so the house feels clammy. With summer afternoons here averaging 91°F and cooling needed from May through September, getting the size right matters for how the house feels, not just for the utility bill.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing just the outdoor unit usually isn't a straightforward swap. The two are matched at installation to work together, and pairing a new condenser with an old coil can mean it never runs at the efficiency it's rated for. Age matters too. If the indoor unit is old enough that it could fail not long after the new outdoor unit goes in, you'd be paying for labor again sooner than you should. A contractor can look at both parts of your system and tell you whether they still match up.
- Do HVAC contractors in Orangeburg need a state license to work on my home?
- A licensed contractor is who you want handling the install and pulling the permit your local building department requires for new central air conditioning work. Ask to see the license number before work starts. New central air conditioners installed since 2023 have to meet a federal minimum efficiency of 14.3 SEER2, and a licensed contractor knows how to install a matched system that meets it.
